				Rock Auto wants $500 for a non vented AC Delco opti spark. Anyone know of better places to buy? I'm leery of remanufactured units and Autozone cheapies. Should I consider aftermarket like MSD or other? Seems like I remember QC issues with MSDs when they first came out but I don't know if they are now a proven product. Any info appreciated.

It doesn't look much cheaper, but I bought a vented opti from Amazon.com made by Delphi. It was more than the cheap ones, but I am hoping it last longer too. This looks to be the Delphi part number for non-vented: Delphi CZ20009 Distributor This is the part number for vented Delphi opit: Delphi CZ20003 Distributor James |
